..l '0 all whom. it may call-unfit.

Be it known that I, J AMES U. Port-en, residing at Pawtucket. county of Providence. State of Rhode Island, a. citizen of the "UnitedStates, have invented cert-sin new -and useful Im rovements in Ring Spinning or Twisting h achines, of which the followin is o. specification.

Vith the spinning mule, the much desired soft finish yarn is produced, but it is at the ex ense of quantity production. For examp e, the carriage may take eight seconds on-the runnin out or stretch in which the twistis being one; three seconds may be taken while the carriage is on the latch; and the run in during which the winding is done takes about three seconds. Thus out of about fourteen seconds, winding, on the bobbin occurs during three of them. In ring-spinning, inasmuch 'as twist and wind take p ece simultaneously, :1. much greater quantity reduction than with themule is possible, ut with the rin -spinmng me.- chines with which I am familiar. and which are praticable, in which the rings more with reference to the bobbins in laying on the thread, the twist must be so tightor close that the spun thread is hard and locking:

in the soft finish which is attained by the mule. I

An object of my invention is to secure in ring-spinnin the soft finish yarn o'l mule spinning an the rapidity of production which is possibl in rm spinning.

Another important OlJJBCb of my invention is to eliminate, or reduce to an uuohjectiouable degree, the torsional strains on the draw or feed rollers bv which the roving; is fed to the bobbins. These rollers sometimes are forty feet long and so small in diameter as an inch for the frontand seveu-eighths for the middle and back rollers. Obviously. rollers so long and so slender. and so weighted as they are to make them grip the cotton, must, when the power to rotate them is applied at one end, as is ordinarily the practice, undergo great torsional deformation when their revolution is started. The consequences of this great twisting strain urn seen in both the machine and its work. First, the rollers themselves rmiy break or be otherwise iniured from the twist. such injury taking place at their journals which are of less. diameter then the rollers, and

where the roller sections are, united or joined. Second, irregularity in the feed of cotton. may result due first to slow movement of the retarded remote portions ot-the rollers which results in thin'yarddut'o insuflicieut feed from the rollers, and second, to sudden speecliu up of theretarded remote portions of the re ers uncler'the reaction of such retarded portions, so that a greater quantity of cotton will temporarily bedehvered to certain of the spinc les then should be. with the consequence that there will be a thickened length of twist that might show and be objectionable in the woven. goods.

Still another important object is to 'zissure the pro or lubrication of the spindle bearings. y the customary oilin derices,esch spindlemust be separately oillad .by'the tipplicution of oil thereto by u boy or attendant. Often by cmelessness or inadvertence he may fail to oil some of them with the result that the spindle revolution ,will be slowed down and wear of and hurt to'the spindle take place thus injuriously effecting broken away of a ring-spinn ng machine emho'dyin mv invention, omitting a portion of the ui der motion gearing for greater clearness;

Before describing in detail the machine shown iii 'thedrawings as one verygood embodiment of my invention I will gwe a genon descriptionthereof. Insulate moving the V reilto carry the rings up and down with reference to the spin les, 1' stutlonurily support the ring rails, and transverse the spindles, mount m a the latter, and the. tin roller which drives t em, on a verticnlly movable carriage to which motion is imparted by a builder motion which in general res cts is of a commonly used construction :1 though in some particulars, as will hereinafter appear, it possesses novel features of importance and value. By keeping the rings stationery and transversing the spindles, it will be seen that the angle .at w ichthe thread runs from the thread guid to the traveler does not change, nor does the Ian h of thread from the guide to the trave er change, as is the case when the rings move. When the rings move and they are at the upper part of the bobbins the thread extends at such an angle from the guide that the thread makes such a sharp turn over the traveler, on its way to the bobbin, that a. weak place in the thread at the turn is readil broken and again the length of thread om guide to traveler is so ort thatif a thin or week place occurs, the pull on the thread by the traveler is apt to break it. To meet these conditions, when a travelin ring is-used, the twist must be made tig t in order to give suflicient strength to the thread to resist breakage, with the result that the yarn produced is hard and lacking in the. uahties which make the soft finish desire le. By using the stationary rings, therefore, the thread between the guideand the traveler has a length and angle that are constant, the length being substantially the maximum, and the angle be' substantially the same as the length an angle that are possible when the rings trave over the bobbins and they are at the bottom or lowest point of their travel. 'I thus remove the conditions that .favor breakage of the thread, and, hence, do not need to make the twist objectionably tight to safeguard against such conditions, and employ a traveler of a weight that will result a twist iving a soft fin sh. The elimination or re notion of the likelihood of breakage of the threads is of greet importance in increasing the output of the machine becauseit saveethe loss of time and trouble required to tie the broken thread,

and the likelihood of an insufliciently filled One of the important advantages that I derive from having the rin -ra.i1 stationery is the ability to use the (:11 e-form separator, which, obviously, is the best form iii-that it controls ballooning throughout the revolution of the 3 indie without hurtful efl'ect on the yarn. %Vith plate-form separators, which is the form that must'be used when the ring-rail traverses over the spindles, the yarn, in ballooning, whips ag'miiw Illd then off them,- wearing the ye'maway and producing d which accumulates and, through 1n unches with the yarn. ith the traversing rail, the tube-form separator cannot be used because in the upper part of the ascending movement of the tin -.rail, there is not room enough below the tread guides to accommodate such tubes.

Another important advantage from the stationary ring-rail is that, being stationary, it can be so firmly or rigidly mounted that trembling or chattering with danger of breaking the yarn between the feed rollers and the bobbins cannot occur.

Instead of driving the feed rollers from a head at the end thereof, I drive them from a head at midlength, and thus by shortening the rollers eliminate or reduce to a negl! ible quantity the torsional deformation 0 such rollers. It is possible for example, with the some number of spindles to re uce the length of the rollers .on either side of the point of application of the power thereto, to rotate them, to substantially half the length of the rollers having the rotating power applied at one end; or the length on each side the point of e plication of power could be greater than half the length of rollers driven at the ends, up to on unobjectionable length, having regard to torsional deformation, and thus the spindle capacity of the machine be increased. The spindles and their tin rollers on either side of the central power applying or rotating head are carried by in ependent carriages and they are 90 connected that they counterbalance one another, so that the weight of one and the parts carried thereby, when descending, helps raise the other and the parts it carries.

Instead of providing for the separate and individual oiling of each spindle in a row, I connect all the oil passages in the bolster case in the same row with a single pipe or tube which at one end has a cup or reservoir into which oil is poured and which is kept at the desired level to assure gravity feed of oil to the spindles and to the pro r level in the bolster case. Thus, with thls method of oiling applied to my ,main fraineincludes two foot pieces, 10, at

20, the endsto the head and foot piece between of spindles. are bearings for the journals la cart-i e composed of a pair of spindle railsfan nect them at the-ends, and at intermediate points, The said carriage is upported by 11, at 'midl ring spinning twisting machine, a sin le carringe supports two rows of spindles, ,t 1c

. oil tubes for the two rows, and the tin roller parts carried thereby, constitutes a unit.

. T'aking p now the description in detail of themachine shown in the drawings, the

opposite ends, and two spaced apart heads,

by which heacs are an ported the driving mechanism. Oneof 1; 1e heads and one of the foot pieces of each pair am-oonnei'zted by two parallel angle Al bars. 13, below the latter are a pair of parallel ring-rails, 14, each supported immovubly by being bolted to a. samson, 15, at midlength, and also, preferably by bolting at which the rails extend. The ring rail has at itsrear edgean integral uandiug flange, 16, that reaches to the be om edge of the front vertical flange of the near angle bar,l13. The ringsmil have rings, 17. of usual form, each witha traveler, 18, and each. concentric with av hole, 19, for the vertical passage or travel of one of the spinclles, 20,.and the bobbin, 21, thereon, the s indies being secured in a row or line of it edesired number to a vertically movable spindle rail, 22. There are two parallel rows of spindles and, therefore, two rails, 22, and the lattenin the case of. each unit lying between a head, 11, and a foot. 10.

, are connected at the ends by a pair of cross bars, 23, and by one or more intermediate -to anidler pulley, 34, journaled in bearcross bars. '23, and at the center of each cross bar, 23, midway betwec1 1 thetwo 'rows of a tin roller, 24, which by bands. 25'. is

,belted'to-the spindles appropriate to'such roller. flhus the two rows of spindles and the tinroller for each unit are mounted on a pair of cross bars, 23, that conthe [spindle rails resting upon i'ertical bolts. 26, that, respect vely, ass through lugs, 27, that project horizoutu y from ver- ,tical slides, 28, that, respectively, are

mounted 'npol'i vertical guides that are boltd or otherwise attached to head, foot, and.

,sanison. "Each slide, 128, has rack teeth,

29, withwhich a pinion, 30, on a horizontal shaft. 31, neshes, (said shaft being rotated by the builder motion hereinafter described so that by the revolution. of said shaft; t e frame which carries the two rows ofspiridles and theassociated tin roller may be ruisiedand lowered, and thereby the verticalltrdyel oifthe sp ndles and their bobblue with reference to the rings, may be and tin roller formi produced. The home rails, 22, since they rest upon the bolts, 26, without being at- .tached to the slides, 28, should there be any horizontal play is necessary to compensate for such imperfection in setting or of material. Bolts, 28, are employed because they enablethe level of the spindle-rail frame tobe independently adjusted, should the supporting frame not be properly leveled. or certain of the bolts, 26, say one on each side, have conical ends that enter corresponding sockets inthe underside of the spindle rails and thereby the carriageis positioned easily. 7

A; most important advantage from my manner of mounting the s indle and tin roller supporting carriage, oosel -restin it on its supports, such as the be ts, 26,15

that such carriage may be assembled as a unit, complete with the spindles tin roller and bands between roller and spindles and then lifted and put into lace upon said supports within the alrea y erected supporting framework composed of the connected head and foot pieces, leaving only the rings-ails and the samson to be put into place a r the said carriage has been placed. Thus erection and assemblage of the machine is easy and convenient. T s

On the shaftof each tinroller in the space between the two heads, 11, a, pulley. .32, from which a belt, 33, passes upward teisha't't pulleys being at right anglesto the tin roller axes. Inasmuch as the spindles one unit rise when those of the other unit descend, it will be seen that the slack i -the belt,'33, caused by the ascent of one, Is exactly taken up by the descent of the other, and, hence, the belt always remains taut, A. screw device, 37, is provided to adjust the idler pulley to g ve the proper tension to the belt, 33.

Thebnilder motion comprises a lever, 88, of substantial len b that is located substantially' midway etween thetwo lines of spindles, and being pivotedne'ar the floor by a pivot, 39, extends upward and near its upper end has a radiall movable slide block, 40., to opposlte si es of which are attached two chains, 41, that extend in opposite directions and respectively pass over dle f 2, located on opposite sides of -the lever and e'ach passing to a sprocket wheel,

43, on one of the shafts, 31,, so that when the layer, 38, swings in one direction, the two shafts, 31, of one unit, (which are geared together by two idlers, 44 meshing with gears, 310, to rotate in thesame direction), will be revolved to move the spindle carriage of that unit downward, and the two shafts, 31, of the other unit will be revolved to move the spindle carriage of the other unit upward, and vice versa, (See Figs. 3 and 9.) The wing to and fro of the lever, 38, is controlled by a heart cam,

45, the peripher of which contacts with a roller, 46, on t e lever, 38, the. lever having a weighted arm, 47, to hold it against the cam. The gearing to drive the cam is described hereinafter.

By havin the two units so tied together by the gearing of the builder motion that one moves up when the other descends, the weight of one counterbalances that of the other, and by having the spindle rails of the same unit connected, or carried by the same frame, so that both move in the same direction, or up and down together, an unbalanced condition is avoided such as would exist if they moved in opposite directions at the same time. The slide block, 40, as usual, is automatically shifted along the lever, 38, or builder arm, to change the length of throw thereof to taper off the ends of the cop, by a pawl and ratchet device, 48, of usual construction, which is adjustable to suit the winding of yarns of various counts, and as the lever stands vertically u right, its upper end, where the ratchet fee is located, is comfortably accessible to an 0 rative for any hand manipulation of sai ratchet device that may be necessary. The ratchet wheel has a handle, 49, for hand manipulation.

order to have the body portion of the cop truly cylindrical, it is essential that variation of the speed of travel of the spindles throu h the rings be avoided, and this can only e accomplished by having1 the point of connection of the lever, 38, wit the chain, 41, move in as near a straight line as possible. I achieve this by my arrangement of the lever, which gives it such length that the are described by said point departs very little from a straight line. 1

It is desirable, in the interest of getting as man spindles as possible in a given space, to set tliem as close together as possible. In locatin them attention must be given to the be looning" of thread in passing from the thread gui es to the travelers. With the rings stationary and the spindles traversing in building up, the efiect of balloonin is greatly diminished, and, hence, the spin es can be placed closer together than is possible where ballooning is greater. This is due to the fact that the length of thread from the guide to the traveler is less than the mariguide is shorter than the miiiinii ni that. i pr eble wen t /asi e i if ring, w t: h m ang e. bji." fl t thread when the ring is he travensing men;- rever.

To enable the thread to be passed into the tube and vet pr ented m entally" es aping hmifmm, an b q e y h s s i 51, may be provided, or as shown in Fig.5, the slit, 510, may be parallel with the'args of the spindle but having the edges lap past one another, the inner edge lapping 1n the direction in which the thread travels around in the tube and therefore in the direction opposite that in which it must move to pass out through the slit. The separator tubes are supported -from the vertical flange of the ring-rail and preferably by means of an arm, 52, by which they are pivoted to a bracket, 53, bolted to said flange, The se crater tubes are supported a substantial distance above the rings to allow access to the travelers in piecing broken ends, the yarn being threaded in the traveler. and also to give them a location which will encompass the ballooning thread where its throw is greatest. These Separator tubes alga useful as shields or guards which the threads from drafts of air occiir ri about the machine which blow the about. This pivotal connection is 'pro'v-idd for convenience in dofiing, for when the spindle is in its lowest position, the tube can be swung upward and against the ring-rail flange. out of the way, asshown by dotted lines in Fig. 4.

The creel, 54, and the feed rolls, 55, are of usual or any desired construction and need not be described in detail. Power to drive the feed rolls is taken by aring from the tin roller of each unit. as a pinion, 56, on the tin roller shaft meshes with a gear, 57, on a shaft having a sprocket wheel, 58, which is connected b a sprocket chain, 59, with a sprocket whee 60, and on a shaft with the latter is a r, 61, which mesllies with an intermediate, that mes es wit a gear, 63, on one of t; ffnt le setw n the 63, a d! mitted to; such gear, 64, on the other front rollers are two intermediates 65, and thus motion is transother feed roller. Power to drive the buildermotion is taken from one ofthe. intermediates, 65. A sprocket wheel, you the shaft of such intermediate, is connected by a; sgarocket chain, 67, with a sprocket wheel, which by bevel gears, 69, one of whichis on a ab 70, rotates the latter which has a worm, 1, that meshes with a worm wheel, 72, on the shaft, 73, to whichflisfixed the builder arm. vibrat The gearconnections with thefeec rollers include pro or change are to enable the sad to changed or different counts an twists.

The tube, .-74,,having the oil cup, 75, at

--one:end for mnveying oil to all the spindles in a row, is clamped to the arm, 76, of the bolster case .by a horizontal block, 77, the tube fitting in a half round groove in the top of the bolster case arm and one in the underside of said block. A single screw, 78,.

clamps the block against the-to .of the arm, andagainst the tube. A- vertica oil passa 79, leads from the bottom of the tube to eliver oil .to the bearings within the bolster case, the bottom of the tube being provided with an outlet, 80 to the top of said assage. Said outlet-his a vantageously ma e by a punch'intro'duced through a hole, 81, in the top of. the'tube, the oi outlet, 80, at the bottom being thereby formed with a lip, 82,

thaten'ters the top of the passage, 79,.and such lip being ofthe passage, t c escape or leakage of oil into 'thejoint between the tube and the bolster arm and clamping block is prevented. Lenka of oil is further prevented by reason of t every close fit between the tube and the bolster case arm and clamp block.'

The "h'ole,81, in the rte? of the tube permits hand-oiling if desi and Minds access to the tube outlet, 80, for ole when necessary Said hole, 81 is oov 11y a cover ate, 88, that fits within a m led groove 84, in the topof the clamp-block, and is pivoted thereto to swing up and down, and said cover has, as usual, a tail, 85. that overhangs the spindle whirl to form a dofing latch.
